Subject: Fix Windows NT API usage in VS 6
X-Git-Tag: v3.0.4~42
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6a616be86fd14aa84608d81077d0f3b30d0fd152;p=thirdparty%2Flibarchive.git

Fix Windows NT API usage in VS 6

VS 6 warns verbosely when WINVER >= 0x0500.  Avoid defining WINVER and
_WIN32_WINNT to higher than 0x0400 on VS 6.  Provide missing API
declarations in archive_windows.h when we do not get them from
<windows.h>.  Provide GetVolumePathNameW because VS 6 does not declare
it regardless of the API version.
